Effects of Different Nutrition on the Biological Characteristics and Antifungal Activity of Metarhizium anisopliae
摘要
Abstract
The biological characteristics of Metarhizium anisopliae were compared with different culture medici, carbon sources and nitrogen sources by measuring the mycelium growth, dry mycelium biomass and conidia production. The results showed that the optimum culture media, carbon source and nitrogen source for the mycelia growth of M. anisopliae was PSA, maltose and yeast, respectively. The PSA, white granulated sugar and peptone were the suitable media, carbon sources and nitrogen sources for the biomass accumulation, which are in contrast to Czapek, lactose and urea. PSA is suit for the conidial production and the maltose and potassium nitrate was the most feasible car bon source and nitrogen source for conidial compared to glycerol and ammonium sulfate. The anti-fungi assay of the secondary metabolites of M. anisopliae revealed that secondary metabolites produced in Czapek liquid media have more inhibition effects than that in SDAY. Similarly, the anti-fungi effects by the secomtary metabolites produeced in the sucrose as the carbon source and/or the peptone as the nitrogen sources is better than those by others.关键词
